System and method for interference mitigation in a wireless communications system

摘要

A system and method for interference mitigation in a wireless communications system are provided. A method for interference mitigation in a controller includes coordinating with other controllers to establish a cooperative agreement, receiving information from a communications device served by the controller, scheduling a transmission opportunity for the communications device based on an indicator and the cooperative agreement, and receiving a transmission from the communications device at the scheduled transmission opportunity.

1. A method for interference mitigation by a controller, wherein the controller is one of a plurality of controllers, the method comprising:
coordinating with other controllers in the plurality of controllers to establish a cooperative agreement, wherein the cooperative agreement specifies a transmit power configuration; receiving a message from a communications device served by the controller, wherein the message comprises an indicator of operating conditions of the device; scheduling a transmission opportunity for the communications device in accordance with the indicator and the cooperative agreement; and receiving a transmission from the communications device at the scheduled transmission opportunity, wherein the controller operates in a communications system, wherein the cooperative agreement further specifies sectoring of a coverage area of each controller in the plurality of controllers, wherein the coverage area of each controller is divided into at least three sectors, and
wherein specifying the cooperative agreement comprises:assigning each sector in the coverage area to one of at least three sector groups;partitioning each sector in each sector group into a number of subzones;sharing partitioning information with the other controllers in the plurality of controllers; andsetting communications parameters for each subzone of each sector of each sector group in accordance with the shared partitioning information.
